The Blue Badge — park where you actually need to be.
A Blue Badge lets you (or someone who drives you) park closer to where you're going — on-street parking that would otherwise be restricted. It costs up to £10 in England, lasts up to 3 years, and some people qualify automatically through PIP, DLA or being registered blind. Since 2019, hidden conditions — severe anxiety on journeys, autism, dementia — can qualify too. It belongs to the person, not the car.
